Mutually exclusive option widget
Synopsis
ttk::radiobutton pathName ?options?
Description
ttk::radiobutton widgets are used in groups to show or change a set of mutually-exclusive options. Radiobuttons are linked to a Tcl variable, and have an associated value; when a radiobutton is clicked, it sets the variable to its associated value.
Standard Options
-class | -compound | -cursor |
-image | -state | -style |
-takefocus | -text | -textvariable |
-underline | -width |
See the ttk_widget manual entry for details on the standard options.

The name of a global variable whose value is linked to the widget. Default value is ::selectedButton.
Widget Command
In addition to the standard cget, configure, identify, instate, and state commands, radiobuttons support the following additional widget commands:
- pathname invoke
Sets the -variable to the -value, selects the widget, and evaluates the associated -command. Returns the result of the -command, or the empty string if no -command is specified.
Widget States
The widget does not respond to user input if the disabled state is set. The widget sets the selected state whenever the linked -variable is set to the widget's -value, and clears it otherwise. The widget sets the alternate state whenever the linked -variable is unset. (The alternate state may be used to indicate a “tri-state” or “indeterminate” selection.)
Standard Styles
Ttk::radiobutton widgets support the Toolbutton style in all standard themes, which is useful for creating widgets for toolbars.
